To caulk a baseboard and trim around doors and windows before painting, you will need the following tools and materials:

Caulk gun
Caulk
Utility knife or caulk smoothing tool
Sandpaper (if necessary)
Painter's tape
Drop cloth
Safety glasses
Here are the steps you can follow:

Clean the surfaces: Before caulking, make sure the surface is clean and free of any debris, dust, or old caulk. You can wipe it down with a damp cloth or use a vacuum with a brush attachment to clean any dust or debris.

Apply painter's tape: Apply painter's tape along the edges of the surfaces you want to caulk. This will help keep the caulk neat and make it easier to clean up any excess.

Cut the tip of the caulk tube: Cut the tip of the caulk tube at a 45-degree angle using a utility knife. The size of the opening should be slightly smaller than the gap you want to fill.

Apply the caulk: Hold the caulk gun at a 45-degree angle and apply a steady and even pressure to the trigger as you move the gun along the gap you want to fill. Apply enough caulk to completely fill the gap without over-filling it.

Smooth the caulk: Use your finger or a caulk smoothing tool to smooth the caulk into the gap. You can also use a dampened finger to smooth out the caulk. Make sure the caulk is level with the surface and there are no gaps or air pockets.

Remove the tape: Remove the painter's tape immediately after smoothing the caulk. This will prevent the tape from sticking to the caulk and ruining the finish.

Let the caulk dry: Let the caulk dry completely according to the manufacturer's instructions.

Sand (if necessary): If the caulk is not flush with the surface, you can use sandpaper to smooth it out.

Paint: Once the caulk is completely dry, you can paint over it as usual.

Make sure to wear safety glasses when using a caulk gun to prevent any accidental caulk from getting into your eyes. You should also work in a well-ventilated area to prevent inhaling any fumes from the caulk.

Make sure the caulk has achieved room temperature before use, ideally leave it in the room overnight.
I personally caulk before painting using a small amount and just wetting my thumb to smooth. Then adding and smoothing to get the effect I'm after. If painting straightaway buy appropriate caulk that can be painted on almost immediately.
If caulking and a clean edge is required; ie. Using a silicone caulk, I always mask to ensure a clean line and lift pretty quickly after smoothing.
To be honest, we probably all do it numerous ways, the final method is a personal choice that feels natural and comfortable.

When caulking only tools you will need is a caulk gun your caulk obviously and also masking tape or frog tape I spray my caulk with washing up liquid and water gives it a better finish always make sure before you caulk it’s free from any dust or else the dust will stick to the caulk and that’s not good

All you will need is a tube of caulk a caulk gun and the most important tool for this job is a wet index finger

Paul · Answer

Normally all caulks do the same thing.
It's in the application.
Cut the tip of the caulk like a pin head then apply.

I WOULD RECOMMEND YOU USE SIMPLE DECORATORS CAULK- IT IS VERY EASY TO USE, JUST RUN ALONG WITH FINGER AND WIPE OFF ANY EXCESS WITH CLOTH. IT CAN BE EASILY SANDPAPERED WHEN DRY. TRY NOT TO USE THE FLEXIBLE MORE EXPENSIVE CAULK, DIFFICULT TO FINISH FOR PAINTING

Gloves and make sure nozzle cut at 45”degrees to get good layer and amount on target area.
Good ventilation.

I like the 1 hour caulk from Travis Perkins . It’s not too wet and is paintable after a hour hence the name 1 hour caulk. Don’t cut the nozzle too wide , a nice tight bead will be ok

To caulk baseboards and trim before painting, follow these steps and safety tips:

Steps:

Gather Tools: Get a caulk gun, painter's tape, utility knife, caulking tool or putty knife, and paintable caulk.

Prepare the Surface: Clean the area to remove dirt and old caulk. Use painter's tape to protect adjacent surfaces.

Cut the Caulk Tube: Cut the caulk tube tip at a 45-degree angle. Start with a small opening; you can always make it larger if needed.

Apply Caulk: Hold the gun at a 45-degree angle and apply a bead of caulk along the joint. Smooth the caulk with a caulking tool or your finger (dipped in water for smoother application). Remove excess caulk.

Let it Dry: Follow the caulk instructions for drying time. It usually takes a few hours.

Painting: Once the caulk is dry, you can paint over it.

Safety Tips:

Ventilation: Work in a well-ventilated area. Caulk can have a strong smell.

Protect Skin and Eyes: Wear gloves and safety glasses when handling caulk.

Clean Up: Clean tools and hands with soap and water before the caulk dries.

Other Tips:

Use high-quality, paintable caulk for better durability and paint adhesion.

Check the weather before caulking; humidity can affect drying time.

Take your time and apply steady pressure on the caulk gun for an even bead.

Following these steps and safety tips will help you properly prepare the baseboards and trim for painting, ensuring a clean and professional finish.
